Title: Improved method for the preparation of solid petroleum pitch
IPC: C10C3/00
Filed: 1955-03-08
Abstract: 764,731. Petroleum pitch. GULF RESEARCH & DEVELOPMENT CO. March 8, 1955 [March 16, 1954], No. 6753/55. Class 55 (2). Petroleum pitch with a Ring and Ball softening point of about 350‹ F. or more is obtained by treating a crude oil to form a residue having an asphaltene content above about 30 per cent and a softening point above about 160‹ F., visbreaking this residue at about 900-960‹ F. and flashing the product at a pressure not exceeding substantially atmospheric pressure to form the pitch as a bottoms product. Crude oil, preferably an asphaltic base crude such as those from Mercy and Eastern Venezulean fields, is subjected to atmospheric distillation in a tower 12 and a heavy bottoms product passes to a vacuum distillation tower 22 to yield a heavy gas oil discharged as distillate through a line 24 and a residual oil which is pumped through a line 26 and heating coils 30 in a visbreaking furnace 32 at a pressure of 50-1000 lb. per sq. in; 15 per cent or less of the charge is converted to gasoline of 400‹ F. end point. The effluent passes through a reducing valve 35 into a flash tower 36 to which steam may be introduced through a line 38. Cracked oil and lighter fractions are distilled and the pitch product is discharged to storage through a line 40. The distillates may pass to a conventional distillation tower 44 for the separation of gas, gasoline, naphtha and gas oil from a heavy bottoms oil. A quench stream of steam, oil, &c. may be recycled to the visbroken effluent to prevent further cracking.
